Global study links daily exposure to ozone pollution to increased risk of death

Green Car Congress

Daily exposure to ground level ozone in cities worldwide is associated with an increased risk of death, according to the largest study of its kind, published in an open-access paper in The BMJ. Ground level ozone is a highly reactive gas commonly found in urban and suburban environments, formed when pollutants react in sunlight.

EEA report finds most Europeans in cities still exposed to levels of air pollution exceeding WHO guidelines

Green Car Congress

The European Environment Agency’s (EEA’s) “ Air quality in Europe — 2019 report ” shows that almost all Europeans living in cities are still exposed to air pollution levels that exceed the health-based air quality guidelines (AQGs) set by the World Health Organization (WHO). About 8% of the urban population in the EU-28 was exposed to PM 2.5

WHO links 7 million premature deaths annually to air pollution; 12.5% of total global deaths

Green Car Congress

Estimates of people’s exposure to outdoor air pollution in different parts of the world were formulated through a new global data mapping. This incorporated satellite data, ground-level monitoring measurements and data on pollution emissions from key sources, as well as modeling of how pollution drifts in the air. g/m 3 annual mean.

SCOPE Biofuels Project Releases Assessment on Environmental Effects of Biofuel Technologies

Green Car Congress

SCOPE is part of the International Council for Science. Low-input cultivation of perennial plants, e.g. from short-rotation forestry and grasslands, may be an effective source of cellulosic biomass and provide environmental benefits (reduced pollution and lower greenhouse gas emissions).
